If you're lucky it'll be the little return screen under the vaccum thingy- check this first as it is usually the cause of surging, and dying when backing off, and you can actually get to it without taking the pump off.
But it's allways better to clean all 8 filters. Yes 8
1 in the tank
4, 1 on each injector
1, above return screen
and the 2 buggers in the pump itself.
1 is the $50 paper filter
the other is the screen in the back of the pump - which takes a certain amount of brute force to get to.
To open the pump-
It is an easy job, but watch the cheesecake screws that hold the pump together. Get them off and throw them away - replace with allenheads. You'll also have to be carefull of the odd shaped o-ring under this, as it will expand if let dry out, and can be a bugger to get back right.
Or do what I did . . .
I got the shits with the pump about 60,000km ago, so I put in an inline filter(about $2 worth) and threw the $50 suzuki part away. Then I simply cut the screen out of the back of the filter. Haven't had a problem since, just replace the $2 inline filter with each service. and check the others every 20,000km.
If you go back through old threads of 3-4 years ago there's books been written on this.
